Can anyone recomend a good leaf vacuum?

Im starting to think about buying a leaf vac.....I was looking at the DR and the cyclone rake. I need something that I can tow behind and sucks up nice. ALL of my lawns are able to be dumped in the street so i just need to move them from point a to the street.....I have seen a few that bag them also and that could be good......any recomendations?? Thanks guys
